Part:BBa_K274210

CrtEBIY under constitutive promoter

This Biobrick is created by putting enzyme cassette CrtEBIY (with individual rbs) of Part BBa_K274200 under constitutive promoter R0011.

Enzyme cassette CrtEBIY (with individual rbs) of Part BBa_K274200 converts colourless farnesyl pyrophosphate to orange beta-carotene (via intermediates geranylgeranyl pyroiphosphate, phytoene and lycopene).

Amount of beta-carotene produced can be measured by photospectrometer with absorbance at 455nm (beta-carotene extraction using acetone).

Further Characterization of BBa_K274210 in MG1655 and TOP10 e. coli has been performed by The 2010 SDU-Denmark iGEM team.
